High currents even in shallow water canwash the dirt out from around your tires orpush your vehicle across slippery rocks orsurfaces.
Never attempt to cross flowing water thatis deeper than your vehicles groundclearance. Even in low currents yourvehicles body surface area can be pusheddownstream and out of control.
Do not cross any body of water that is fastflowing and rising, wait for the flow rate toreduce.
Determine exit points that are downstreamof your entry point to allow for drifting.
If there are other vehicles ahead, wait untilthey’ve left the water. Unsettled water canmake a safe passage more challenging.
Know your vehicle’s abilities and be ableto recover it if something goes wrong.
Keep the doors fully closed during a watercrossing.
Vehicles used to traverse water regularlyshould be periodically inspected for signsof water ingestion in all of the vehicle'sfluids. If water is found inside your vehiclefluids, service your vehicle or see anauthorized dealer.
After driving through water and as soon asit is safe to do so, check the brakes, horn,lights, and steering wheel to make sureeverything is still in working order.
Avoid Getting High-Centered
Always keep available ground clearancein mind and pick a route that minimizes therisk of catching the underside of the vehicleon an obstacle and getting high-centered.
Freeing A Stuck Vehicle
WARNING: Do not spin the wheelsat over 34 mph (55 km/h). The tires mayfail and injure a passenger or bystander.
Recovery hooks are mounted to thevehicle's structure and are used to pull outthe vehicle from a surface or location whenstuck. Recover your vehicle using varioustowing apparatus attached to yourrecovery hook such as winch, open hook,or strap.
Note:Do not use recovery hooks torecreationally tow your vehicle. SeeRecreationally Towing Your Vehicle (page338).
If your vehicle gets stuck in mud or snow,you may rock it out by shifting betweenforward and reverse gears, stoppingbetween shifts in a steady pattern. Pressthe accelerator in each gear.
Note: Do not rock your vehicle if the engineis not at normal operating temperaturedamage to the transmission may occur.
